Material examined. Holotype: ♂, grassland around Unheung Temple (35°47′05″N, 128°36′13″E, alt. 205 m), 2.6 km north of the summit of Mt. Choijeong, Gachangmyeon , Dalseong­gun , Daegu, 31 October 2006, B. K. Seo . Paratype: 1♂, same data as holotype .

Etymology. The specific name comes from the type lo­ cality, Gachang Township.

Diagnosis. The male palp of L. gachangensis n. sp. is similar to that of L. songniensis Seo, 2015 in the femur with many strong spines, the tibia without apophysis, and the tarsus without transverse depression, but can be easily distinguished from the latter by the conical embolus, the blade­like prolateral sclerite, the blade­like median sclerite, the skinny triangular retrolateral sclerite with serrated tip, and the tarsus unbranched retrolaterally, with two spurs at tip and much longer proximal prolateral spur ( Fig. 1 E­G).

Description. Male (holotype). Total length 1.76. Habitus as in Fig. 1A. Carapace brown, and 0.84 long, 0.72 wide; fovea linear, distinct. Clypeus height 3.5 times of
